Java while循环不循环

Question

我的摇摆界面中有以下按钮

    private void solveButtonMouseClicked(java.awt.event.MouseEvent evt) {                                         


    step1(); 


}   

它调用step1();

   private void step1(){

//step 1 solving the white cross around the yellow middle
        while( (!(F2.getBackground().equals(white))) & (!(F4.getBackground().equals(white))) & (!(F6.getBackground().equals(white))) & (!(F8.getBackground().equals(white)))){


         textArea.append("cnt");

        //top three pieces solved
        if(F2.getBackground().equals(white) && F4.getBackground().equals(white) && F6.getBackground().equals(white)){
            //solve F8 
            while(!(F8.getBackground().equals(white))){

                //check right side
                if(R2.getBackground().equals(white)){right(); right(); downinv(); rightinv(); rightinv();}
                else if(R4.getBackground().equals(white)){rightinv(); downinv(); right();}

问题似乎是step1()中最外层的while循环.它应该继续运行,直到满足所有条件,但它只是在一次迭代后停止,我无法弄清楚原因.如果我删除外部while循环step1()完全按照按钮的多次按下每个步骤进行.救命!

Answer 1

你提到你要保持循环,直到所有的比较都是真的.

如果任何条件成立,它现在编码的方式将退出循环.

而不是

while ( !boolean1 && !boolean2 && !boolean3) {

尝试

while ( ! (boolean1 && boolean2 && boolean3) ) {
